How long can one reasonably expect a recip compressor to last compared to a scroll??

Depends n a lot of things but given the same conditions a recip will outlive a scroll.

They are a better design with less tolerances to work with,

PS Scroll is not new technology been around for almost a century they just could not get it to work and still have trouble with it.

Its only on the market because it does not re-expand compressed vapor, so it is more efficeint but not more durable

Hey Swamp,

I think they all know better than to go against me,I can't say that I know how it feels to be on the wrong side.Its something that I just don't have much experience at .

I can only imagine that it must be aggravating,disappointing and immensely unbarable for them.

It probably leaves them with a feeling of remorse and anxiety leading to endless hours of reevaluating the way they look at things in the field,only to realize that they really don't understand a whole lot of this stuff.

Mmm....

But why do units with scrolls have 10 year warrenties and recips only 5 year??

I personally thing eddy is wrong too in this case but dont being warranty into it, thats marketing and has nothing to do with reliability in an of itself.

Now I for one thing a scroll can handle liquid much better, it's sump has more capacity to handle liquid and acts as accumulator in a small way, it may get noisy but a flimsy suction valve (you will notice many scroll mfg's dont require a cch and starting components are not required as often). Granted they dont like a vacuum while operating but flooding is much more likely. I also feel that all things being equal in proper operation, a scroll is quieter. Since this is the residential section, I assume we are talking hermtics and not including semi's or open drives as I prefer being able to repair them then replace them. Scrolls do indeed have closer tolerances which you may see as a liability but it also has alot to do with efficiency. Scrolls tolerances are based on heavier materials not light weight materials used in the head of a recip (valves and pistons). Also Scrolls generaly include a check system to prevent refrigerant on the head at start up.

Listen, all compressors require several things to last and as long as either has them, they will both last a long time.
Motor Cooling, lubrication, proper application and voltage to name a few. Subtract any one and the compressor's life is reduced.
